There will never be a concerted effort to devise a canonistic version of a Middle-earth video game. That went out the door when Middle-earth Online (MEO) was abandoned for the farcical Lord of the Rings Online (LOTRO). I was among several well-versed gamers who spent a few years offering input into the original MEO, but the developer (Turbine, may their name be forever cursed) abandoned the original concept for a World of Warcraft knock-off renamed LOTRO that Turbine wanted to market as direct competition for said WoW.
I alpha and beta tested LOTRO, levelled out several times with several characters, and became violently ill at the inane end result. I never played a Middle-earth based game again. As a farewell present, I offered a blistering review of the aborted offspring of Turbine, and I am sure the name Morthoron the Dark Elf is still whispered fearfully in dark corners of their misbegotten forums.
